Issues with Flash and the actual quality of those games aside, what I really miss from that period of the internet was that children could use it safely. There's no spaces for children on the internet anymore and I think that's really sad, nine year old should be playing Hannah Montana dress-up not get eating disorders from TikTok influencers
Edit for clarity: I didn't mean to come off as though I think the internet was ever safe for unsupervised children because that's not what I believe. What I was trying to say is that the loss of spaces made for children, with adequate content curation and moderation, pushed children on social media which is awful for them
